The story tells that the Giant’s Causeway was built by Finn McCool as a walk way to fight the Scottish giant Benandonner.
Finn fell asleep before going across to Scotland and he woke up to find the Scottish giant appearing on the horizon. Finn realised Benandonner was much bigger than himself and ran to his wife Oonagh wondering what he should do. Oonagh disguised Finn as a baby and made him curl up in an enormous cradle. Benandonner saw the huge ‘child’ in the cradle and began to wonder what size his father would be. Benandonner returned to Scotland and destroyed the Causeway as he returned home.
